My car was getting timing pulls on COBB Stage 2+ Aggressive even though local stations advertise 93. On the same gas, Stage 2+ Sport (91 octane map) is clean with no timing pulls at all.

The same gas with some off the shelf octane boosters produces clean timing graphs on 93 aggressive.

So I'm wondering, is the gas around here just that bad a quality of 93 octane? or is it possible there is another issue that may be causing the timing pulls on said "93 octane"... maybe carbon build up or slight mis-fires that don't throw codes?

We use Torco octane booster in the race cars. It really helps combat knock...

More than likely it's just bad gas. How does the sport map look?

perfect haha no timing drops on any cylinders with the same gas and no additives.



its just strange because literally 3-4 different stations/brands that I've tried have all produced the same results with multiple timing pulls on their "93 octane"... which is why i was wondering do you think it could be another small issue?


maybe something on my car or in my gas tank that is making the mixture lower octane? (just spitting our random bs that sounds good that could possibly be a reason haha)

just weird 3-4 different stations all advertising 93 octane are doing the same thing.

nice recent post, you just can't get above being a dick. I'll be sure to take something you say completely out of context next time. You should work for CNN

^^Straight from your visitor messages.... Interesting

Not sure who you're buying from, but buy your gas (if possible) from a Top Tier Gasoline Retailer (http://www.toptiergas.com/retailers.html). The gas stations listed here are held to a standard that ensures the quality of the octane is legit, regardless of where you're buying it from.

[dfv2]

BUMP for evidence a protuned vehicle by any shop with any of the following:

e85
hybrid turbos
a different map sensor
double digit timing
meth

OR

Bump for news or ETA of the following:

ATR
v4 maps out of beta
fabled "race" or meth maps?

OR

Bump for the answer to whether I will go the full length of summer waiting for the above while the piggy fans get xmas twice a month!!

i buy from shell and chevron mainly and they both give me the same results. so thats why i ask if it could be my car?

Well since both are on the Top Tier Retailer list, and you're buying 93 at both, I'd say it's one of two things:

1. One of those gas stations has a shitty tank that's allowing contaminents to diminish the quality of the 93
2. Your car

I'd try running the 93 from one station for a week consistently, and then try the other -- See if one's 93 is actually better than the other's. Otherwise, when was the last time you changed your fuel injectors? It's interesting that even though you're using 93 consistently, that the octane booster (which doesn't yield a significant increase in octane rating) helped your car run better.

That's odd. Just to cover the basics, when was the last time you changed your plugs?
How bad are the timing drops? Every once in a while, I'll have a couple cylinders make a correction. If just one or two cylinders make a -3 correction it's not a big deal.
I remember you posting logs up before, but I'm sorry I can't remember how they looked.

exactly, which is why im starting to think it is my car. but i just dont know what it could be... my injectors were checked and some replaced last august during the recall for the hpfp.

changed plugs like 8k miles ago... swapped out with oem.

and the drops were badd haha they look knock induced... consistent pulls in the same place/same cylinders across multiple cylinders. and usually 3-4 degrees drops... never had clean timing produced on any gas in my area ever haha

Any word/rumors about the COBB getting E85 maps?? Or has anyone blended 93/E85 and data logged? Interested/considering a 2:1 mixture of 93:E85 instead of messing around w/ race gas, octane booster or toluene.

those will come after official V402, Race/meth maps.

should be getting close when Rob gets back.

My guess is you can run E85+Meth on there "race" map (just a guess though)

If you're having timing corrections you could try starting at a15% mix and working your way up until your timing corrections are gone.

No timing issues, I'm just wondering since E85 offers performance gains similar to 100 octane, but is less expensive then 93/100 octanes + doesn't require that you run meth. Guess we're just all waiting on those new maps now.

[rader1]

If you have access to e85 you can always get an ATP tune. However, since you don't have any bolt-ons you can't really push it to its potential.

I have VRSF DPs, Helix FMIC, ER CP + Forge DVs sitting in my basement, the install is getting scheduled as we speak

To save money you should just do the FMIC and CP yourself. It shouldn't take more than 3 hours and is pretty easy to do.

The DPs are a PITA

+1. CP and FMIC really aren't that bad once you get used to working in tight spaces. I looked at the DP's and knew instantly that wasn't happening with me under the car. My local tech did the install and gave me the precious gift of a few extra hours time.
